Impact Valuation

All decisions, big or small, involve trade-offs. Whether straightforward or complex, there are always pros and cons.

For decades, one key issue has dominated decision-making: financial capital. Whichever option is more profitable is pursued, and impacts on the other capitals (natural, human and social) are often overlooked. But this outlook is starting to fade, and consequently, leading organisations are beginning to consider more seriously outcomes across a more holistic set of economic, environmental and social impacts.

This process – assessing and valuing impacts across multiple capitals – is known as impact valuation, and it is a vital tool for all forward-thinking organisations.

In an increasingly complex world, impact valuation enables more informed, sustainable, and resilient decisions. It reduces the risk of unintended consequences and unlocks powerful opportunities to maximise value.

The many services we offer under this theme fall into four key stages: Learn, Assess, Communicate, Act.

  • We work with companies to quantify and value the environmental and social impacts of their operations and supply chains. This enables the creation of integrated profit and loss accounts, helping organisations identify priority areas for action and maximising positive impact.

  • We support development finance institutions (DFIs), impact investors, and private family investors in assessing and monitoring investments. Impact valuation helps estimate the SROI, provides recommendations to enhance societal benefits, and enables retrospective impact assessments to inform future projects.

  • We conduct extended cost-benefit analyses (E-CBA) to quantify and value the impacts of different project or investment options. This enables a more comprehensive understanding of net impacts and strengthens decision-making for stakeholders.

  • We develop ‘alternatives assessment’ chapters for major infrastructure project environmental and social impact assessments (ESIAs). Using a combination of monetary valuation and multi-criteria analysis, we quantify and value a range of impacts to identify the optimal source, location, or materials while meeting lender requirements.
